CALENDAR-CLOCK.

SPECIFICATION forming part of Letters Patent No. 235,605, dated December 14-, 1880.

Application filed September 21, 1880.

To all whom it may concern Be it known that 1, JAMES E. YOUNG, of Genoa, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Calendar-Clocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in calendar-clocks; and it consists in an attachment which can be applied to the front of the works of any clock, and which will take up but very little room.

The object of my invention is to provide a separate and independent calendar attachment which can be applied to almostany clock, and which attachment will exhibit nothing but the day of the month, the day of the week, and the month itself.

Figure 1 is a front view of the clock, showin g the parts of the calendar which are exposed to view. Fig. 2 is a plan view of the mechanism, with the dial-face of the clock removed. Fig. 3 is a detached view of the month-wheel and the operating lever. Figs. at, 5, 6, 7 are detail views.

A represents the winding-post of the clock, which has the spring B and gear-wheel O attached to it in the usual manner. This gearwheel 0 meshes with the wheel D, which forms a part of my attachment. Upon the shaft of this wheel D is attached a double-lever, E, which is longer at one end than the other. The longer end of this lever catches in the teeth of the wheel F, which is secured to one end of the shaft G, which has the cylinder H at its other end, and upon which cylinder are marked the days of the week. The wheelF has seven teeth, each one of which corresponds to aday of the week, and as the wheel D revolves every twenty-four hours it will readily be seen that at each one of its revolutions the wheel F is moved forward one notch, thereby changing the dayof the week, which is exhibited through an opening in the dial-face of the clock. This change in the day of the week is regulated so as to take place about 12 oclock at night, and after the cylinder has been moved forward so (Model.)

as to present a new day it is prevented from turning backward by means of a suitable spring and ratchet.

The shorter end of the lever E catches in the notches of the wheel I, which has thirty teeth to represent the thirty days of the month. This wheel I has secured to it a cam, J, which revolves with the wheel, and which operates the bent lever J, which lever J operates in connection with the month-wheel K. Upon the same sleeve as the wheel I and cam J is a lug or projection, L, which revolves with them, and which, at each revolution, catches in one of the teeth of the wheel M, which is secured to and operates the wheel K. Also secured to'the same sleeve with the wheel I and cam J and the projection L is the dialplate 0, which has marked upon it the thirtyone days of the month. The sleeve to which all the parts just enumerated are secured fits over the sleeve that the hour-hand is fastened to. secured a projection, P, which, at each revolution of the dial-plate, catches in one of the twelve teeth of the wheel R, which is connected to the cylinder S, upon which are marked the names of the months of the year, and thus turns the cylinder far enough to present a new month through the proper opening in the dial-face of the clock. The days of the month, numbered upon the dial-plate O, are also exhibited through a suitable opening in the dial-face of the clock, and thus the month, the day of the month, and the day of the week are exhibited through the dial-plate of the clock without any other part of the mechanism being shown. The cylinder S is also provided with a suitable spring or ratchet, so as to prevent the cylinder from turning backward after it has been moved by the dialplate 0.

The monthly wheel K has notches cut in its periphery to represent the months for four years, so as to correspond to the leap years, in which there are twenty-nine days in February. The lever J has a catch, T, to catch in the notches in this wheel K, near the inner end of the lever, and at the outer end of the lever is secured a spring, V, by which the lever is drawn back into position after it has been raised upward by the cam J on the sleeve On the under side of this dialplate O is with the wheel I, and to the end of the le 'er itself is attached a pawl, W, which catches in the teeth of the wheel I for the purpose of pushing the wheel around one, two, or three days, according as there. are thirty-one days in the month, or twenty-eight or twenty-nine days in February. The notches in the periphery of the wheel K are larger and deeper for February than for any other month, so that when the catch T on the leverJ catchesin one of these notches it will remain in it until the cam has had time to revolve around, and this cam raises the lever J up sufficiently high so that when the hand of the lever J slips oft of the cam the pawl on its end will force the wheel I around two or three days, according as to whether the catch is caughtin the notch which represents the February of leap year or the February of the other three years. Where it is caught in the notch which represents the February or leap year the pawl will move the wheel only two notches forward, so as to bring it to the first of March; but if the catch is caught in the notch which represents the February of the other years the pawl will move the wheel three notches forward, when the lever slips off of the cam.

Where the month has thirty-one days there is no perceptible notch made in the periphery of the wheel K for the catch T to catch in; but when the month has thirty days the catch catches in one of the smaller notches in the wheel K.

As above stated, this attachment is to be applied over the face of any clock, or almost any, and will be operated by the mechanism of the clock, although the works have not been specially intended for it.

As the two cylinders representing the days of the week and the months of the year are adapted to be turned by hand to the opening in the dial-plate of the clock, they can be readily changed to any day or month that may be preferred, and the dial-plate O, which represents the days of the month, can be turned in a similar manner.

In place of the revolving disk or ring with the figures on it for the days of the month, the figures for the days of the month maybe made on the dial, outside of the numbers which represent the hours of the day, and a pointer or hand attached to the sleeve of the calendar to point to the days of the month.

Having thus described my invention, I claim 1. The combination of the wheel D, having secured to its shaft the lever E, for operating the cylinder which represents the days of the week, and the wheel which represents the days of the month, substantially as specified.

2. The combination of the wheel I, cam-lever J, the projection for catching in the teeth of the wheel which operates the monthly wheel K, the wheel K, having notches in its periphery, a spring, and a pawl, substantially as shown and described.

I11 testimony that I claim the foregoing I have hereunto set my hand and seal this 6th day of September, 1880.
